6 Pack Mini Digital Thermometer Hygrometer,Indoor Temperature and Humidity Gauge Meter Monitor Fahrenheit (℉) for Home,Greenhouse,Jars

Seem to be accurate, right on par with the houses thermostat... Fits in large mason jars... 6 for the price is definitely worth it

These are fantastic. I glue them to the inside of airtight containers to store 3D filament and bam - instant moisture-monitored storage. Easy to use, durable and good for price.

Not completely accurate (see photo of them all together with different measurements) - so I would not recommend in areas where accuracy is importance such as animal or delicate plant habitats etc. However, they are close enough to get the gist of the information for indoor and outdoor spaces, and for that I give 4 stars

These hygrometers are a great deal for the price. Check out the photo—the one on the right has desiccant beads in it and it’s reading a lower humidity percentage, while the one on the left (no beads) is showing a higher reading. They’ve been sitting next to each other in the same spot for about two weeks now, and the difference stays steady. That makes total sense: the desiccant is pulling moisture out of the air inside its little chamber, so it reads drier, and the one without is just showing the real room humidity. Honestly, the fact that they’re both holding stable and behaving exactly how you’d expect gives me a lot of confidence they’re accurate. Super happy with these for the money.

I have these in every room of my house. The temperature and humidity levels are great to be aware of, especially in this super hot weather! The temperature levels vary a degree or two when side by side, but exact measurement is not necessary for me.

Heh well not exactly what I expected. I ordered the 1/4" thick but this is two 1/8" thick strips sewn together by a single stitch down the center of each. Worked out for my need anyway. Used this to replace the gasket on my hot water heater plate for the burner assembly. I ended up needing only the 1/8" so I just cut the stitch and applied the gasket properly.

Inexpensive so i was able to place them throughout the house near the themostats as a check

Very good info supplied by these

Good for jumping spider enclosures or other small invertebrates. Not perfectly accurate but gives a good enough estimate.

Très pratiques et abordables. Je voulais ces petits gadgets surtout pour savoir la température dans mon garage vu qu'il est chauffé seulement au bois et avec un appartement au dessus, on va éviter que les tuyaux gèlent🪵 6 petits thermomètres pour mettre un peu partout dans la maison et dans le sous sol aussi. J'adore! Mon seul ick est que c'est en Fahreneit et je suis plus habitué en Celsius. Il y a t il une façon de changer les degrés? Sinon c'est pas si grave, je me suis fait une feuille de conversion.

I ordered these knowing they were not super accurate scientific devices, and am happy with what I got. 5/6 work fine and the % humidity shown was close to what my weather station was showing.

These are obviously not highly scientific devices, but they are accurate enough for my intended uses. Each one is a little bit "off" from the next, even when placed together in the same space for an extended period. But none were very far off the mark and readings between each device showed only about +/- 1%. Close enough for the price!!

Then I got these and the batteries sit as they are supposed to be, unlike those round ones I bought earlier, just happy I found these, will buy more soon. They are way better. Bought more, mine that I bought long ago are sticking to what ever they touch, time for new ones. Best I’ve ever tried, thank you.
